Works like a charm! I had to zap my pRAM to fix a problem with audio output levels, but I don't think this really constitutes a bug (and 9.1 may not even have been the cause of the problem).
I upgraded from 9.0.4 to 9.1 on a PM G4, 384MB RAM. OS 9.1 is significantly faster and it is ROCK solid. It's crashed only once over the course of a week, while 9.0.4 crashed every day or so. As usual, 9.1 crashed while I was using the network browser and dialing in via ppp with tcp/ip.
9.1 gives me a slight fps boost in Open GL games...nothing extraordinary but I'm an eye-candy slut so I'll take whatever I can get.
